DescriptionChrysocolla, CuSiO3-nH2O (hydrated copper silicate), is an attractive blue-green mineral that provides a unique color to the mineral world. Chyrsocolla is perhaps more appropriately a mineraloid than a true mineral. Most of the time it is amorphous, meaning that it does not have a coherent crystalline structure. However, at higher temperatures it does demonstrate a distorted crystal structure that seems to be composed of Si4O10 sheets. Chrysocolla forms in the oxidation zones of copper rich ore bodies.
